Application filed December 6, 1924. Serial No. 754,312.

The following is a full, clear and exact description, such as will enable others Skilled in the art to which it appertains to make and to use the same, reference being had to the accompanying drawings'which illustrate the preferred form of the invention; .though it is to'be understood that-the invention'is not limited to the exact details of construction shown and described, asitis obvious that various modifications thereof within the scope of the claims will occur 'topersons skilled in the art.

Figure 7 is a view similar to Figure 6 showing another modified form of swivel pin, and 1 Figure 8 is a view similar to Figures 6 and 7 and showing a further modified form of swivel pin.

An object of this invention is to provide an improved mine car hitch which may be used for connecting mine cars and will be provided with car engaging links having special construction at their adjacent ends and connected by a swivel pin which is of an improved construction and will permit the swivel to have rotary movement in'the cross heads at adjacent ends of the links and further permit the links to have longitudinal movement upon the swivel pin without danger of the pin being broken.

Another object of the invention is to so construct theswivel pin that side sections forming the same may be securely held. in spaced relation to each other by a separattings '15; -'These openings taper inwardly,

asshoyvnin Fig.- 2, so that'the links may have, tilting gmovement upon the swivel pin 16 without danger of the pin being bent or broken or the cross heads broken..-

- wThe swivel pinmay .be formed as shown in-Fig. 2 or as shown in Figs. 6, 7 or 8.

These various ,forms are very similar to each other but are somewhat different in theirj details of construction. I The form 1 shown in Fig.2 will first-be described. Re-

ferring to Fig. 2, it will be seen that the swivel pin is provided with longitudinally extending.sidesections '17 which are provided ,at their, ends with enlarged head forming extensionsf18. These sections 17 when placed contact with each. other do not form a perfect circle but when-spread apart by the wedge 19, as shown in Fig. 5,

these sections will have their arcuate side faces constitute arcs of an interrupted circle which will be approximately of a diameter corresponding to the'diameter of one of the openings 15 at its inner end. The head forming side extensions or flanges 18 of these sections 17 are of greater sectional area than rthe'intermediate sections 17 but when placed in' contact with each other before insertion of the wedge these head formingportions or fiangeswill provide a circularhead'having a diameter small enough to permit 'of its being passed through the openings 15. It will thus be seen that before the wedge is put in place the sections forming the swivel can be placed in contact with each other and pass through the openings 15 in the cross head 14: of the links The wedge will then be put in place as shown and in' the form shown in Fig. 2 this wedge will be secured against moving lon- Inn from the sections 17 at one end ofthe swivel..-

In Fig. 7,-the wedge-26 is a short wedge which will be forced intoplace between the sections 17- forming the swivel-pin. These sections 17 are-provided tit-their ends-with tongues 27 --which normally extend longitudinally of-theswivel-as indicated by dotted lines so that thewedge can beeasilyput in place.
